While I love the DX4000 I find the fan noise too loud. In my workspace I have 2 workstations, LaserJet, Inkjet and peripherals etc., and the room is very quiet.
At night when the DX4000 is powered down I find the other items fan noise is very low. But the DX4000 seems to be on full speed all the time even at very low use on the network.
Is the fan speed adjustable? In these days of 120mm plus fans that really work to whisper, this unit is a screamer by comparison.
Is an quiet fan replacement an option?
